              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Another afternoon storm kept us closed through sunset with clouds and
nearby radar, but dissipated quickly so that we were able to open around
the end of twilight.  Seeing was very good on initial focus, but after a
few hours it deteriorated to middling-poor and stayed there for the rest
of the night.  More clouds returned second half, moving rather
unpredictably and not really matching the satellite.
Telescope and instruments behaved well, except that Don had intermittent
trouble with Center Sel not working, perhaps because he was using TUI
v1.9.4.  There was a period during second half where internet difficulties
and clouds conspired to cause significant delay in acquisition of a star;
I put this down as weather since I think we would have dealt with the
internet faster if we weren't sitting around waiting for the clouds to
part.
